Khoom Description

Nyob rau hauv cov txheej txheem ntawm cov roj thiab roj extraction, tom qab fracturing kev kho mob ntawm siab kaw siab thiab tsis tshua muaj permeability mineral deposits, cov kua yuav tsum tau txhaj rau hauv lub pob zeb puag kom tshaj lub pob zeb tawg lub zog ntawm lub tsim, ua rau tawg nyob rau hauv lub pob zeb formations nyob ib ncig ntawm lub wellbore. tsim ib qho channel nrog cov peev txheej ntws siab. . Thaum lub sij hawm tus txheej txheem no, cov roj fracturing proppant plays lub luag hauj lwm nyob rau hauv kev txhawb cov pob txha tawg los ntawm kev kaw vim muaj kev ntxhov siab tso tawm, yog li tswj cov conductivity siab, cia cov roj thiab cov roj ntws mus zoo, thiab nce ntau lawm.

kev ua tau zoo proppants xaiv cov txheej txheem

Cov txheej txheem xaiv rau kev ua tau zoo muaj xws li: lub zog compressive txaus thiab muaj peev xwm tiv thaiv hnav, muaj peev xwm tiv taus lub zog thiab kev sib txhuam thaum txhaj tshuaj, thiab kev txhawb nqa zoo ntawm cov pob txha pob txha; qhov txheeb ze ntawm cov khoom yuav tsum yog tsawg los pab txhawb nqa cov downholes; Qhov loj me me yuav tsum ua kom tau raws li cov qauv tsim ntawm cov qhov dej sib txawv, feem ntau yog 0.4 ~ 0.8mm, lub roundness thiab sphericity yog ntau dua 0.9, thiab cov khoom sib xws thiab qhov saum npoo yog du, thiab nws cov nqi turbidity yuav tsum tsawg dua 100 degrees kom tau txais qhov siab tshaj plaws muaj peev xwm hloov tau; ntawm qhov kub ntawm 200 degrees Celsius, yuav tsis muaj tshuaj lom neeg cuam tshuam nrog cov kua dej tawg thiab cov dej hauv cov dej, thiab qhov siab tshaj plaws ntawm cov kua qaub solubility yuav tsum tsawg dua 7%.
